국은주,김종만 대한물리치료학회 2015 대한물리치료학회지 Vol.27 No.3

Purpose: The aim of this study was to compare EEG topographical maps in patients with chronic stroke after action observation physical training. Methods: Ten subjects were recruited from a medical hospital. Participants observed the action of transferring a small block from one box to another for 6 sessions of 1 minute each, and then performed the observed action for 3 minutes, 6 times. An EEG-based brain mapping system with 32 scalp sites was used to determine cortical reorganization in the regions of interest (ROIs) during observation of movement. The EEG-based brain mapping was comparison in within-group before and after training. ROIs included the primary sensorimotor cortex, premotor cortex, superior parietal lobule, inferior parietal lobule, superior temporal lobe, and visual cortex. EEG data were analyzed with an average log ratio in order to control the variability of the absolute mu power. The mu power log ratio was in withingroup comparison with paired t-tests. Results: Participants showed activation prior to the intervention in all of the cerebral cortex, whereas the inferior frontal gyrus, superior frontal gyrus, precentral gyrus, and inferior parietal cortex were selectively activated after the training. There were no differences in mu power between each session. Conclusion: These findings suggest that action observation physical training contributes to attaining brain reorganization and improving brain functionality, as part of rehabilitation and intervention programs.

PURPOSE: This study examined the foot pressure distribution using the sprinter and skater patterns of coordinative locomotor training. METHODS: Thirty healthy adults, comprising 11 men and 19 women, participated in the study. All the participants performed patterns in sprinter pattern conditions 1–3 and skater pattern conditions 1–3, and were measured using a pedoscan to determine the applied foot pressure distribution. RESULTS: The participants significantly differed in the big toe during the sprinter pattern. As a result of the post hoc test, opposite and opposite sprinters showed a significant difference from the same sprinters (same sprinter; 21.33 ± 5.92, opposite sprinter; 23.54 ± 5.41, and reopposite sprinter; 24.14 ± 6.46). There was a significant difference in the lateral side during the skater pattern. As a result of the post hoc test, reopposite and same skaters showed a significant difference from opposite skaters (same skater; 49.88 ± 5.75, opposite skater; 48.78 ± 5.64, and reopposite skater; 51.15 ± 5.37). CONCLUSION: The foot pressure was distributed toward the hallux and fifth toe according to the sprinter and skater patterns of coordinative locomotor training.

The aim of this study was to determine the effect of application of action observation physical training on sit to stand and balance in people with chronic stroke. 19 subjects who are suffering from chronic stroke were randomly assigned to either the experimental group(EG)(n1=10) that was performed physical training plus action observation, or the control group(CG)(n2=9) that was carried out only physical training. The intervention was implemented for 30 minutes, 5 times a week for 3 weeks(total 15 sessions). Action observation training for the subjects from the EG was conducted by watching a video tape recorded previously with consisting of 4 tasks reaching and grasping target object in sitting and standing positions,and then the physical training was practiced. The subjects from the CG practiced the physical training in similar pattern with that of the EG. For the measurement of clinical function of the subjects, sit-to-stand(STS) test, timed up and go(TUG) test, and static balance were executed before and after the interventions. In the groups, the STS time and static balance score were significantly improved after the intervention(p<.05); however, there were no significant differences between the groups(p>.05). In the TUG test, the EG showed a significant improvement after the intervention(p<.05), but not for the CG(p>.05). Further, there was a significant difference in the TUG scores between two groups(p<.05). These findings suggest that the action observation training may be beneficial to enhance the physical training of patients with chronic stroke.

본 연구의 목적은 중증장애인의 자립생활능력을 자가평가할 수 있는 지표를 개발하여 자립생활훈련 전과 후 자립생활 수행에 필요한 기능에 변화가 있었는지를 알아보기 위함이다. 현재 우리나라에는 자립생활 패러다임의 확산으로 센터 및 각종 사업이 실시되고 있으나 장애인들이 자신의 자립생활 수행이 어느 정도인지 혹은 서비스를 제공받은 이후 자립생활능력이 향상되었는지 저하되었는지를 스스로 평가하는 측정도구가 없어 자신의 자립생활능력을 객관적으로 판단할 근거 자료가 없는 실정이었다. 이에 중증장애인 자립생활 자가평가지표를 개발하여 2001년부터 2004년까지 자립생활훈련을 수료한 장애인 334명(뇌병변 172명, 척수흉수 83명, 척수경수 79명)에게 훈련개시 시와 훈련종료 시 2번에 걸쳐 29개 항목(신체적, 정신적, 사회적 기능으로 구분)으로 구성된 자가평가지표를 5점 척도에 의하여 스스로 평가하도록 하였다. 조사결과 개발된 중증장애인 자립생활 자가평가지표는 0.8, 0.9이상의 높은 신뢰도지수를 보여주었다 또한 전체 훈련생 자립생활 자가평가 점수는 훈련종료 시가 훈련개시 전보다 7.8점이 향상되었고 연도별로는 매년 훈련종료 후에 자가평가 점수(6.2점~11.3점)가 증가하였으며 장애유형 별로는 지체경수(11.0점), 지체흡수(9.3점), 뇌병변(5.6점) 순으로 점수가 증가하였는데 이는 모두 통계적으로도 유의한 차이가 인정되었다. 따라서 자립생활훈련이 자가평가 점수에 긍정적인 영향을 주었고 매년 일관되게 효과가 있었던 것으로 나타났으며 장애의 정도가 중증일수록 더 효과가 있는 것으로 평가되었다. 또한 자립생활 자가평가지표가 개발됨에 따라 장애인 스스로가 자신의 자립 정도를 파악할 수 있는 계기를 부여하였다고 본다. The objectives of this study are developing self-evaluation criteria in order to enable the serious disabled persons to evaluate themselves and illustrating the changes of their independent living abilities between the before and after of the training for independent living by using the index of self-evaluation criteria newly developed in this study. In the present, various services and projects for independent living caused by the spread of the paradigm of independent living are being carried out in Korea but the serious disabled persons in Korea do not have certain tool or standard to self-evaluate the level of their independent living abilities objectively because there is no criteria of the self-evaluation in order to realize whether their level of living is improved or not and measure how. much the level of living was improved after taking the services. Thus, this study developed the self-evaluation criteria of independent living ability for the serious disabled and made 334 disabled persons(The brain lesion group were 172 persons, The paraplegic group were 83 persons, The tetraplegic group were 79 persons) who had finished an independent living training program from year 2001 to 2004 evaluate themselves at the beginning of training and the end of the training by using the self-evaluation criteria with 29 items (divided by physical, mental and social independence) and 5 point scales. Based on the result of the above research, newly developed self-evaluation criteria showed high confidence level of over 0.8 and 0.9. In addition, the self-evaluation scores of the all trainers were improved by 7.8 points from the beginning of the training to the end of training, and the scores were increased in order of tetraplegic group(11.0 points), paraplegic group(9.3 points) and brain lesion group(6.5 points) in the type of disabilities, that showed statistically meaningful differences. In result, it was proved that independent living training programs had not only a positive effect on self-evaluation scores but also a more effect on the more serious disabilities. By developing these self-evaluation criteria, a certain chance also should be provided for the serious disabled to evaluate themselves.

Ultrasound (US) elastography is a valuable imaging technique for tissue characterization. Two main types of elastography, strain and shear-wave, are commonly used to image breast tissue. The use of elastography is expected to increase, particularly with the increased use of US for breast screening. Recently, the US elastographic features of breast masses have been incorporated into the 2nd edition of the Breast Imaging Reporting and Data System (BI-RADS) US lexicon as associated findings. This review suggests practical guidelines for breast US elastography in consensus with the Korean Breast Elastography Study Group, which was formed in August 2013 to perform a multicenter prospective study on the use of elastography for US breast screening. This article is focused on the role of elastography in combination with B-mode US for the evaluation of breast masses. Practical tips for adequate data acquisition and the interpretation of elastography results are also presented.
